%X To measure the air-sea heat process in a small scale by using an infrared camera is of great scientific significance. However, the imaging nonuniformity of the uncooled infrared focal plane array used in the infrared camera has severe influence on the observation of sea surface temperature distribution. By using the calm water surface as a blackbody, the nonuniformity of the infrared camera is corrected and the stripe noise is removed. By comparing the Normalized Mean Square Error (NMSE), signal-to-noise ratio and standard deviation of the images processed via different filtering methods, the Gaussian filtering method is found to be more effective.
